Técnicas para separar múltiples respuestas en radares secundarios operados en modo S

Secondary Surveillance Radar (SSR) is a radar system that allows the identification and monitoring of specific targets in space. High traffic density produces a mixture of several overlapping signals in the receiver unit. To avoid this problem and to achieve a correct decoding of the data an uniform linear array is proposed for the implementation of the receiver. In this context, various algorithms are introduced. This algorithms use the structural information of the antenna array or the structure of the input data to manage an effective separation of the different response signals. The aim of this paper is to present a new algorithm (MDDB) which combines both information to generate a better estimation, making comparisons with the different methods implemented today.
